Is the HTML Analyzer correct?

Hi I have this HTML in my Product Landing Page Project. When I do the HTML Analyzer it shows the findings below. But it seems correct to me. Can You tell me what I’m missing?

    <section id="how-it-works">  
  <iframe id-"video" width="560" height="315" src="" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

Special characters must be escaped : [ < ].

Special characters must be escaped : [ > ].

Tag must be paired, no start tag: [ ]

I found it. It should have been <iframe id=“video” not <iframe id-“video”

Thanks again.
